Platybunus has two, and Megabunus one British representa- 

 tive. They are of small size, and are to be sought for among 

 heather or dead leaves ^ 

 in spring or early \ 

 summer. 



Fam. 2. Ischyro- 

 psalidae. Coriaceous 

 Phalangids, with eye- 

 turret far removed from 

 anterior border of 

 cephalothorax. Max- 

 illary lobes of second 

 pair of legs rudi- 

 mentary, in the form 

 of tubercles. Legs 

 similar, without " tro- 

 chantin." Multiarticu- 

 late tarsi. 'Tarsus of 

 pedipalp without daw, 

 and shorter than meta- 

 tarsus. Pedipalps long 

 and horizontal. 



This family includes 

 a small number of 

 large or moderate-sized 

 Phalangids, which are 

 found occasionally in 

 thick moss, or in caves, 

 in mountainous regions of the south of Europe, and belong 

 to the genera Ischyropsalis and Sabacon. There is a North 

 American genus, Taracus. 



Fam. 3. Nemastomatidae. Coriaceous Phalangids, with 

 cephalothorax fused with the first Jive segments of the abdomen, 

 forming a scutum. Eye-turret near anterior border. No maxillary 

 lobe on second coxae. Similar legs, without " trochantin." Multi- 

 articulate tarsi. Tarsus of pedipalp without claw, and shorter 

 than metatarsus. 



There is but one genus, Nemastoma, in this family, and the 

 members of it are, as a rule, rather small and dark 1'halangids, 

 which live under stones or in moss or debris, and are found in 



Fio. 236. Olifjolophus spinosus. (After 

 Pickard-Camliridge.)
